Im trying to create a rick roll script, and this is what I have so far. I have dock dodger so it doesn't appear on someone's dock when it runs, but now I've ran into a brick wall. I need a little help with some commands to add this script to iCal. Lets say every hour, every day. I also would appreciate some help with some code to add it to someone's login items. Thanks!

Code:

say "never gonna give you up, never gonna let you down"
open location "http://bringvictory.com/"
delay 5
say "Never gonna give you up. Never gonna let you down. Never gonna run around and desert you. Never gonna make you cry. Never gonna say goodbye. Never gonna tell a lie and hurt you"
delay 30
application "Safari" quit
say "Oooh
We're no strangers to love.
You know the rules and so do I.
A full commitment's what I'm thinking of.
You wouldn't get this from any other guy.
I just wanna tell you how I'm feeling.
Gotta make you understand.
Never gonna give you up.
Never gonna let you down.
Never gonna run around and desert you.
Never gonna make you cry.
Never gonna say goodbye.
Never gonna tell a lie and hurt you.
We've known each other for so long.
Your heart's been aching, but.
You're too shy to say it.
Inside, we both know what's been going on.
We know the game and we're gonna play it.
And if you ask me how I'm feeling.
Don't tell me you're too blind to see.
Never gonna give you up.
Never gonna let you down.
Never gonna run around and desert you.
Never gonna make you cry.
Never gonna say goodbye.
Never gonna tell a lie and hurt you.
Never gonna give you up.
Never gonna let you down.
Never gonna run around and desert you.
Never gonna make you cry.
Never gonna say goodbye.
Never gonna tell a lie and hurt you.
(Ooh, give you up).
(Ooh, give you up).
Never gonna give, never gonna give.
(Give you up).
Never gonna give, never gonna give.
(Give you up).
We've known each other for so long.
Your heart's been aching, but.
You're too shy to say it.
Inside, we both know what's been going on.
We know the game and we're gonna play it.
I just wanna tell you how I'm feeling.
Gotta make you understand.
Never gonna give you up.
Never gonna let you down.
Never gonna run around and desert you.
Never gonna make you cry.
Never gonna say goodbye.
Never gonna tell a lie and hurt you.
Never gonna give you up.
Never gonna let you down.
Never gonna run around and desert you.
Never gonna make you cry.
Never gonna say goodbye.
Never gonna tell a lie and hurt you.
Never gonna give you up.
Never gonna let you down.
Never gonna run around and desert you.
Never gonna make you cry.
Never gonna say goodbye.
Never gonna tell a lie and hurt you."
